This week we’re digging into AdTech surveillance. We will discuss how advertisers track people across the internet to serve targeted ads. People generally rely on adblockers to prevent this. However, researchers have recently identified new methods to protect people’s privacy – including some that sabotage targeted advertising. This week we discuss these methods with our guests Jiang Zhang (USC) and Haroon Muhammad (UC Davis). For more information, see the paper, "HARPO: Learning to Subvert Online Behavioral Advertising" (https://arxiv.org/pdf/2111.05792.pdf).
